Exploring pharmacist prescribing practices in general practices for atrial fibrillation in England: a qualitative study using the theoretical domains framework

Abstract

Introduction: Pharmacist roles in primary care are evolving, with increasing involvement in long-term condition management. An example is their crucial role in the management of atrial fibrillation (AF), particularly in prescribing and monitoring oral anticoagulation therapy. However, their experiences and challenges in this area remain underexplored, particularly within the context of general practice.

Aim: This study aimed to explore the experiences, perceptions, and challenges of independent prescribing pharmacists when managing and prescribing for AF within general practice, using the Theoretical Domains Framework (TDF) to guide enquiry and analysis.

Method: We conducted a qualitative study underpinned by the Theoretical Domains Framework (TDF), which informed both the interview guide and the analytic coding framework. Independent prescribing pharmacists working in general practice in England were purposively recruited via professional networks; eligible participants were patient-facing and had experience prescribing for atrial fibrillation. One-to-one, semi-structured interviews were conducted via Microsoft Teams® in August 2024, audio-recorded, transcribed verbatim, and returned to participants for checking. Recruitment proceeded until thematic saturation. Two researchers independently applied the framework method, resolved discrepancies by consensus, and mapped final themes to relevant TDF domains.

Results: Twenty pharmacists took part in the study (9 men, 11 women; age 25-52 years), providing perspectives from a range of experience levels. Four overarching themes emerged: (1) confidence and experience in prescribing, (2) perceived role and responsibilities, (3) barriers to effective prescribing, and (4) strategies for effective prescribing. Pharmacists with extensive AF experience demonstrated higher confidence, whereas less experienced pharmacists relied on guidelines and colleagues. Perceived roles ranged from central to supportive within multidisciplinary teams, with some uncertainty about role boundaries. Key barriers included incomplete access to patient records, limited training, and workload pressures. Strategies to support prescribing included continuous professional development, decision support tools, and peer consultation.

Conclusion: The study emphasises the challenges pharmacists encounter in managing AF, highlighting the need for clearer role definitions, improved access to patient data and ongoing peer support. Addressing the identified barriers through targeted interventions could enhance the effectiveness of pharmacist-led AF management in general practice. Future research should evaluate interventions designed to support pharmacists in this evolving role.
